The Spectral Energy Distribution of Post-Starburst Galaxies in the NEWFIRM Medium-Band Survey: A Low Contribution from TP-AGB Stars

open access: yes, 2010
Stellar population synthesis (SPS) models are a key ingredient of many galaxy evolution studies. Unfortunately, the models are still poorly calibrated for certain stellar evolution stages.

The Origin of [OII] in Post-Starburst and Red-Sequence Galaxies in High-Redshift Clusters [PDF]

open access: yes, 2010
We present the first results from a near-IR spectroscopic campaign of the Cl1604 supercluster at z~0.9 and the cluster RX J1821.6+6827 at z~0.82 to investigate the nature of [OII] 3727A emission in cluster galaxies at high redshift. Of the 401 members in

A comparison of the galaxy populations in the Coma and distant clusters: the evolution of k+a galaxies and the role of the intracluster medium

open access: yes, 2003
The spectroscopic properties of galaxies in the Coma cluster are compared with those of galaxies in rich clusters at $z \sim 0.5$, to investigate the evolution of the star formation history in clusters.

Abundance diagnosis of E+A (post-starburst) galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2007
E+A galaxies are characterized as a galaxy with strong Balmer absorption lines but without any [OII] or H$ $ emission lines. The existence of strong Balmer absorption lines means that E+A galaxies have experienced a starburst within the last $

No Metallicity Preference in Fast Radio Burst Host Galaxies

open access: yesThe Astrophysical Journal Letters
Fast radio bursts (FRBs) are millisecond-duration extragalactic radio transients of unknown origin, and studying their host galaxies could offer clues to constrain progenitor models.

266 E+A Galaxies Selected from the Sloan Digital Sky Survey Data Release 2: The Origin of E+A Galaxies

open access: yes, 2005
E+A galaxies are characterized as a galaxy with strong Balmer absorption lines but without any [OII] nor H$\alpha$ emission lines. The existence of strong Balmer absorption lines indicates that E+A galaxies have experienced starburst within recent one ...

SHELLQs-JWST Unveils the Host Galaxies of 12 Quasars at z > 6

open access: yesThe Astrophysical Journal
The advent of the James Webb Space Telescope (JWST) has opened new horizons in the study of quasar host galaxies during the reionization epoch ( z  > 6).

Post-starburst Galaxies in SDSS-IV MaNGA: Two Broad Categories of Evolutionary Pathways

open access: yesThe Astrophysical Journal
We study the size–mass relation (SMR) and recent star formation history (SFH) of post-starburst (PSB) galaxies in the local Universe using spatially resolved spectroscopy from the final data release of MaNGA. Our sample includes 489 PSB galaxies: 94 cPSB
